o Lgf lnvenfor Francis H. Alamb to the burner and emerges from thepassages '19 in fine jets. The air from 'the manifold passes through theburner body 6 and passages and 2l. The air entering the burner escapesthrough the aperture 17, z'. e., through' the annular passage leftbetween the walls of the aperture and the burner. As this passage isconsiderably restricted the air attains great velocity so that on com.

ing in contact with the oil jets it breaks the same u into 'a finespray. This breaking upx` of t e jets is further assisted b the air wich blows into the slots 18 an centers in a forwardly moving blastbetween the oil' jets. 'The air-entering the passage 20 escapes throughthe annular apeture 24, and

` forms la code of air around the oil jets which is cau ht and carriedforward. The oil spray ',m'the burner strikes against the rod 31 andis.,thereby thrown into the air core issuing from the aperture 24. Thisrepeated mixing of the oil with air produces a resultant gas of veryhigh thermal eilicienc7 which burns with a clear smokeless flame. Theair from'the passage 21 enters the combustion chamber through thepassages 28, and providesl an'additional supply of oxygen to insureperfect combustion. The updra from the bottom passage 28 also tends tolift the fiam'e above the bridge 26. It will be understood that afterthe. burner has been in operation for a short time the combustionvchamber and casing? become very hot, and that by passing'the airthrough the passages 20 'and A21 it is heated sutiiciently to insureperfect evaporation of the oil and at the same time prevent the blast ofcold air. from striking the flame. The bridge wali throws the fiame upand concentrates the same and also serves to stop particles of oil andsoot, and prevent their entrance into the' furnace. The purpose .ofsloping the rod 31 is that should liquid oil collect thereon and rundown, it will not soak into the brick as it would i'fth'e rod werevertical, but will be evaporated in its passage down the rod by the airemerging .from the bottom aperture 28.

Havin declare t at what I claim is4 1. A device of the characterdescribed comprising a casing an air passage at the back of said casing,a combustion chamber Vsupported by said casing, an air passage in theside of the combustion chamber for admittinv air thereto, a burner bodyassociated with t e combustion chamber, a burner inv said body, adefiector supported within said combustion chamber, and a baille locatedin the mouth of said combustion chamber, for throwing the dame upward.

2. An oil burner comprising a body hav ing a taperingoutlet, a tipsupported in said outlet whereb a tapering annular orifice is formed,sai tip having a plurality of oil ducts spaced from the center thereof,means for heating air and a tapering annular oritice from said airheating means surrounding said first named orifice.

3. A device ofthe class described comprising a burner, a casing, an airpassage at the back of said casing, a second air passage at the sidesand bottom of the casing, a combustion vchamber supported by the casing,an air manifold connected to said burner and passages, an annularorifice leading from the first passage into the combustion chamber atthe rear, conduits leading from the .second passage into the combustion'chamber at the sides and bottom.

4. A device of the class described comprising a burner, a casing havingair passages therein, a combustion chamber supported in said casing, anair manifold connected to said burner and air passages, an air inlet atthe rear of the combustion chamber arranged to form a cone of air infront of the burner,

means for throwing the oil from the burner into said air cone, airinlets at the sides and bottom of the combustion chamber, means forcontrollin the iiow of air through said air inlets an Ameans forconcentrating the flame of combustion.

-In witness whereof I have hereunto set my hand in the presence of twowitnesses.
